Perhaps you should try some spelling variations:
"historia un mathematical" » "historia in mathematical", "historia en matematicas", "historia in mathematics", "historia una mathematical", "historia con mathematical", "historia de mathematical"
"historia en mathematica" » "historia con mathematica", "historia in mathematical", "historia en matematicas", "historia del mathematica", "historia de mathematica", "historia y mathematica"
"history en matematica" » "history en matematicas", "history la matematica", "history el matematico", "history and matematica", "history of matematica", "history a matematica"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("history en matematica") OR ((("historia en mathematica") OR ("historia un mathematical"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history en matematica\") OR (((\"historia en mathematica\") OR (\"historia un mathematical\"))))*".
• Removing quotes may allow a broader search: (( history en matematica ) OR ((( historia en mathematica ) OR ( historia un mathematical ))))*.
